LOCK.

SPECIFICATION forming part of Letters Patent No. 593,436, dated November 9, 189'?.

Application filed J'une 29, 1897. Serial No. 642,852. (No model.)

To all whom, it may concern.-

Beit known that LTHoEsTEN ALBIN THEO- DOR RYDBERG, a subject of the King of Sweden and Norway, and a resident of Stockholm, Sweden, have invented certain new Improvements in Locks, oi' which the following is a specification.

The object of the invention is an improvement in locks the tumblers of which are straight-guided and each consisting of a pin or bar or the like, severed crosswise in two parts, lying end against end, and one of them actuated by a spring that pushes that part in the locking position; and the invention consists therein that each tumbler consists of such a severed pin or bar (solid or hollow) surrounded by one, two, or more concentric tubes,severed and spring-actuated in the same manner as the pin, or it may be of only two ormore concentric tubes made to slide in each other. Those tumblers are brought in the position to unlock by pressure of the key against the parts not directly acted upon by the spring-pressure. Such a set of tubular tumblers may be arranged either so that the key is inserted rectilinearly in the longitudinal direction of the tubes and acts by steps in the end of the key or so that the key, being provided with inclined faces at its side or sides, is to be inserted at right angles against the longitudinal direction of the tubes and acts on the tumblers by pressure either at the insertion of the key or by turning the latter. One, two, or more such sets of tumblers may be used in the same lock.

On the accompanying drawings the invention is shown applied to apadlock in Figures 1 to 3 and to a bolt-lock in Figs. 4 to 6. Fig. 1 is a section of the padlock, and Fig. 2 the under side of the same. Fig. 3 shows one of the legs of the bow. 5 a plan, and Fig. G an end view, oi' the boltlock.

In the padlock shown, 1 is the body of the lock.

2 is the bow, the one leg 3 of which is cylindrical and movable in a boring in the body of the lock. v

4 and 5 and 7 and S are the parts of two concentric tubes.

6 and 9 are the springs.

10 and 11 are the parts of a pin within the Fig. 4 isa section, Fig.V

tubes, and 12 its spring, which in the example shown on the drawings abuts against a bottom provided in the surrounding tube 8. When the key 13 is outdrawn, the ends of the parts 4, 7, and 10 are pressed against the bottoms of the borings in the leg 3, (indicated by dotted lines, Fig. 1,) and the bow 2 cannot be pushed outward. Vhen the key is inserted and pushed inward,the tumblers are brought into the opening position by the inclined faces of the key, as shown in Fig. 1', and by continued pushing of the key the bow 2 is pushed outward, so that the pin 14 in the other leg of the bow leaves its hole in the body of the lock, whereupon the bow can be swung outward and the lock is opened.

15 is a pin in the leg 3, which at the swinging outward of the bow slides on the face 16 and supports the bow. The handle of the key limits the movement of the bow outward. In certain cases it is necessary to guide the tubes by means of key and groove, as indicated at 16 in Fig. 3. In the example represented there are shown two sets of tumblers, but therealso can be one or three or more sets, if desired.

By the aforesaid it is easy to understand how the tumblers operate in the lock shown in Figs. 4 to 6, but the key 17 acts on them with its end, and there is only one set of tumblers. The tumblers are numbered as in Fig. 1 and are fitted in a casing 18, provided with slots and shoulders for the key. The casing 18 is movable in a casing 27, inserted in a door 26 or the like. The casing 18 is iixed to a disk 19, which is provided with a pin 20, entering into a slot 23 in a plate 22, attached to the bolt 21 of the lock. Vhen the key 17 has been inserted through the keyhole and pushed to the bottom or against the shoulders in the casing 18, the tumblers have the position shown, and one can turn the key and operate the bolt 2l by the pin 2O and open the door.

24 is a cylinder arranged in a boring in the bolt and actuated by a spring 25.

When the bolt 21 is thrown to open the lock, the cylinder 24 is thereby brought axially in line with the tumblers 5, 8, and 1l, and under the action of its spring 25 this cylinder 24 will push the said tumblers back against the bottom of the boring (indicated ICG by dotted lines in Fig. 4E) in which they work, so that the bolt 21 cannot be again thrown out tovthe position shown in the drawings, except by the insertion of the key 17, which, acting `upon the tumblers 5, 8, and ll, will then push the cylinder 24 back into the bolt 2l and free the latter.

I claim as my invention- 1. A lock having tumblers composed of concentric tubes each in parts placed end to end, substantially as described.

2. A lock having tumblers composed of concentric tubes, each in parts placed end to end, and springs adapted to press upon the tubes as and for the purpose set forth.

3. A lock having a tumbler composed of a spring-actuated tube in two parts end to end In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
